It looks like you're expecting runghc to work with cygwin paths: it
doesn't. Our policy with GHC on Windows is that the runtime environment
has no cygwin dependencies at all, so runghc is a plain Windows
executable that searches your Windows %PATH% for executables named
ghc.exe. Hence it can't find /usr/local/bin, because that directory is
really c:\cygwin\usr\local\bin.
BTW, /usr/local/bin is an unusual place to install ghc on Windows. I'm
not sure whether everything will work properly.
Cheers,
Simon
